INSECTIGIDE Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed. October 80, 1907'. Serial No. 399,893.

To all whom it may concern."

Be it known that I, HENRY S. DELAMERE, a citizen of the United States, residing at Ferndale, in the county of Humboldt, State of California, have invented certain new and useful Improvements in'Insecticides; and I do hereby declare the following to be a full,

. clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and 'use the same.

This invention relates to improvements in insecticides, and it has more particular referwingled insects.

ence to a liquid composition for attracting and poisoning flies and similar noxious e composition consists of the following ingredients combined in the proportions stated, viz: arsenic trioxid, (white arsenic) 1280' grains, oxid, of cobalt 2560 grains, asafetida'60 grains, brown sugar 1 pound, and suflicient water to make a gallon. In the production of this composition the I oxid of cobalt, arsenic trioxid and asafe'tida are thoroughly comminuted and mixed together in a mortar, the mixture being then added to the'water in which vthe sugar has been reviously dissolved, the water having been oiled rior to the addition of the sugar thereto. T e whole composition is then placed in a can and sealed.

In use the mixture, after having been thoroughly shaken is poured to the desired amount, upon aplate or shallow pan which is then placed at the desired spot, the insects being attracted theretoby the odor of the asafetida present in the mixture. The arsenic trioxid and the oxid of cobalt, by reason of their poisonous nature positively kill the insects when the latter have eaten the composition, and do not merely deaden them as do the powdered compositions usually em loyed. The oxid o cobalt present in t e composition settles to some I HENBY s. DELAMERE. Witnesses: l l
